Irritable bowel syndrome (IBS) is a common disorder of the intestines. It can cause cramping,
stomach pain, gas, bloating, and changes in bowel habits. Some people with IBS have constipation (difficult or infrequent bowel movements). Others have diarrhea (frequent, loose stools). Some people have both. Eating more or less fiber can help control these symptoms. High-fiber/low-fat diet, If you have constipation, a high-fiber diet can help. Try to eat 20 to 35 grams of fiber each day. Use food labels to tell how many grams of fiber are in foods you eat. Important points to keep in mind: The foods that have the most fiber are grains (especially bran), whole-grain breads and cereals, fruits, and vegetables. Foods high in soluble fibers (like oats, peas,
and beans) have been shown to ease both constipation and diarrhea. Read food labels. Look for breads and cereals that list whole-grain or whole-wheat first. Put more fiber in meat dishes by adding pinto beans, kidney beans, black-eyed peas, bran, or oatmeal. Look for cooked and
ready-to-eat cereals with at least 5 grams of fiber per serving.
